ContentsTo the StudentReady™ New York CCLS Practice is
a review program for the Common Core Learning Standards for Mathematics. In this practice test, you will answer 78 Math questions (68 multiple-choice, 6 short-response, and 4 extended-response).
Your teacher will explain how you will do the practice test and record your answers. Be sure to follow the directions. As you complete the practice test, answer the questions carefully. Use the Answer Form on page 57 to record your answers to the multiple-choice questions. Remember to fill in the answer bubbles completely. If you change an answer, you must erase your first answer fully. You will write out your answers to the short- and extended-response questions in the book.
While you work on the practice test, use the Testing Tips below. Read these helpful tips carefully. They can make you a better test taker.
Testing Tips for Answering Multiple-Choice Questions
• Read each question carefully before you try to answer it.
• Be sure you know what the question is asking you to do.
• Cross out any answer choices that are not reasonable. Then make your choice from the remaining choices.
• Read the question again. Check that your answer makes sense.

Which reasoning proves m/4 5 458?
A Since /2 and /5 are alternate interior angles, m/5 is also 628. The sum of the measures of /3, /4, and /5 equals 1808. m/2 1 m/5 5 1248. Therefore, m/4 5 568.
B Since /2 and /5 are corresponding angles, m/5 is also 628. The sum of the measures of /3, /4, and /5 equals 1808. m/3 1 m/5 5 1358. Therefore, m/4 5 458.
C Since /1 and /5 are alternate interior angles, m/5 is also 628. The sum of the measures of /3, /4, and /5 equals 1808. m/3 1 m/5 5 1358. Therefore, m/4 5 458.
D Since /2 and /5 are alternate interior angles, m/5 is also 628. The sum of the measures of /3, /4, and /5 equals 1808. m/3 1 m/5 5 1358. Therefore m/4 5 458.

Which reason best explains why Derek’s line is a better model for the data?
A Since point J is close to the other points, the line would also be close.
B Since the line has a positive slope, it can be used as the line of best fit.
C Since point K is a data point, it can be used to find the line of best fit.
D Since point K is an outlier, the line would be below the other data points.
